EX_NAVIERSTOKES7 3D Example for incompressible stationary flow in a curved pipe.

[ FEA, OUT ] = EX_NAVIERSTOKES7( VARARGIN ) Sets up and solves stationary flow in a curved circular channel. The inflow profile is constant and the outflow should assume an offset parabolic profile. Accepts the following property/value pairs.
